It appears that whomever is greenlighting new series responds quite well to any pitch in which the protagonist is not the person you think she or he is. You could argue that's true for a lot of their popular shows — Weeds (mom is a drug dealer?), Dexter (police investigator is a serial killer?), Secret Diary of a Call Girl (she's a call girl?) — but it's especially true of three of their comedy series, two of which air new episodes tonight, and one of which debuts tonight.
I know TV network executives like to replicate success whenever they can (see: NBC's Thursday night, in which The Office spawned Parks and Recreation, for merely one of a million such examples). So point-counterpoint taken.
